well, I have never had power available where I store my rig for the winter. Now, I do. At a pole barn I rent, I have a 30 amp outlet, I lever my rig plugged in all summer long, and the fridge on during my camping season. No, it is all winterized. I usually remove the battery and leave it all winter on a battery tender. Right now, the battery is still in the unit, and I have it plugged in.
Has anyone done this all winter? will it maintain the battery? is it ok for the inverter?
Any opinions on this would be great. I have no issue taking it out, but it is nice leaving in there and keeping unit plugged in. then I can go in and do things in the off season. Everything else is all winterized.

When we stored our Rv's out in the Northern Ohio winters we left the batteries in and the RV plugged into 50 amps. We ran a string of 60W light bulbs inside the unit to control moisture. We did that for many years. We are now long timers and do not do winters so our Montana is plugged in 24/7/365.

Mine stays plugged in to a 20 amp circuit while in storage for the winter, and any other time I am not using it. Never a problem in 10 years. I do check the battery water regularly and add if needed. You could also disconnect the battery and use the battery tender.

I don't leave the fridge for long periods as mine builds up ice in the freezer over time.

thanks for the tips I will give it a try.
My battery is sealed, so I cant check the water in it.. don't think I can anyways.
I only have it plugged in right now for the battery charger really, everything else is off. I don't mind keeping the fridge on all summer long, it defrosts itself so I don't get excessive ice buildup

My choice would unplug disconnect Battery Terminal and use a Battery Tender on the battery only! Or just take it home like you did in the past
Not sure how secure your Pole Barn is, That nice Cord could disappear!!

We leave ours plugged in 24/7 also. The converters in the Montana's are pretty smart. It goes into a storage mode after a certain amount a time and every so often will run a equalize mode to help extend your battery life. I do check my water level every so often as I don't have maintenance free batteries.

its all one unit, ill give it a shot this year, I do like being able to go in and out to do things when it is stored. Pretty safe over there, cameras, etc.....I just didn't want to burn out my inverter that's all..

We have 50amp here at our residence for our camper when not at a campground. I'm not sure about this but I suspect that leaving the residential fridge running might actually be better for it than shutting it off? Seems like every appliance that I have turned off and on in the past didn't hold up very well.....

We had a 30' sailboat for years and were fortunate enough to have shore power when on dry dock. Kept it plugged in to trickle charge the batteries. We do the same now with our 5er for the time between summer camping ending and leaving for warmer temps at the beginning of the year. I blow out the lines, empty and wash out the water heater, put AF in the p traps and toilet, empty the fridge and leave the doors on it slightly open to prevent mold.
